Title: Fixed head type digital audio tape recording and reproducing device
Inventor: KIRA TORU
IPC: H03M7/30
Filed: 1991-06-10
Abstract: PURPOSE:To compress data without lowering tone quality by recording a digital signal with data-compression using the encoding of audio signal with multiplex adaptive band conversion. CONSTITUTION:After the audio signal is converted to a digital signal, by passing through a compression circuit 21 using the encoding of the audio signal with the multiplex adaptive band conversion, a required data amount is compressed to 1/4-1/8 without lowering the tone quality of acoustic feeling. Thus, the multiplex adaptive band conversion, a signal amount processed per unit time is reduced at the same proportion as that of the data compression amount, a circuit is simplified. Further, the consumption amount of a tape is reduced and the practicality of the device is increased since the recording data amount is reduced.

Filed: 1988-06-07
Abstract: PURPOSE:To obtain an information display device in a distribution operation processor capable of automatically testing matchedness by testing connection to any of a power supply end or a load end of a plurality of section switch terminals from the attribute information of the section switches connected to a line section and judging whether the section switches are normal or not. CONSTITUTION:Since a normally-open section switch 3-5 in section switches connected to a line section E1 has no forward information, the section switch 3-5 is removed from the conditions of a test. Two power supply ends (a terminal number 1) and one load end (a terminal number 2) are used as the terminals of the nodes of residual three normally-closed section switches 2-31-2-33. When the load end existing in the line section is only employed at that time, the normally-colsed section switches are closed successively from the power supply side to the load side, and no service interruption section and power butt section is generated. Power butt is generated when no less than one load ends are used, and there is a stoppage section when the load end is zero. Accordingly, the mathcedness of a power distribution system is tested automatically, and the information of the system can be displayed.

Abstract: PURPOSE:To enable the adaptation to a material capable of recording and erasing information, by preparing an alloy, which takes different spectral reflectances on the basis of the change in a crystal structure by quenching and heating, by compounding Cu and Ga being main components in a specific composition. CONSTITUTION:A Cu-Ga alloy containing 21-30wt% of Ga is formed into a foil shape. This foil shows a whitish yellow color and shows a yellow color at room temp. after heating. When this whitish yellow foil is scanned by laser beam, a yellow line is formed. When the yellow line is subsequently scanned by laser beam having a large spot diameter and low energy density, said yellow line changes to the original whitish yellow color. That is, this alloy has different crystal structures and spectral reflectances between first, temp. higher than room temp. and second temp. lower than room temp. The change in the reflectance can be discriminated in a wavelength region excepting 400 and 520nm. The recording material utilizing this alloy is enabled in the recording and erasion of information and the operation thereof can be performed repeatedly.

Abstract: PURPOSE:To provide a device which can suppress power supply noise and in which stable operation is performed by incorporating a voltage dropping circuit consisting of MOS transistor using a boosted potential for a word line in a restore circuit of a bit line. CONSTITUTION:A voltage dropping circuit consisting of mainly nMOS transistor Q2 is incorporated in a restore circuit 6 of a bit line. A boosted potential of a boosting circuit 4 which generates boosted potential VPP higher than power supply voltage VCC is supplied to gate electrodes of the transistor Q2 in order to operate a driving circuit 5 with high voltage and power supply voltage VCO is supplied to a drain. Consequently, voltage VDDS of source side of the transistor Q2 is lower than VCC and becomes always VPP-Vt (Vt is threshold voltage of the transistor Q2). Therefore, AC type noise which is decided by di/dt due to operation of a voltage comparator generated at the time of completion of restore can be reduced.
